Blade was one of four
Bison Troopers to be experimented and turned into cyborgs. He has undergone
rigorous physical training. Their mission is to eliminate Guile
and his forces.

In Blade's ending, he
is revealed to be Guile's brother Gunloc (a character from Saturday Night
Slam Masters), who has infiltrated Shadaloo as a deep cover agent. His
appearance, and backstory, should be noted to not be part of Street Fighter
canon (more important to note is that Gunloc in the official Japanese canon
"is not" related to Guile in any way, shape, or form.)

In battle, Blade uses
attacks that involves a great deal of concealment. He has an array of weapons
at his disposal including a bazooka, a stun rod and knives which are hidden
within his red uniform.
